/* FIX 1: the Hermes CHARACTER watermark inside the orb. A pre-processed data
   URI — the 512px character art, feathered to a circle so its edges fade to
   transparent (the orb appears to CROP it, with no square box) and luminance-
   weighted to a warm near-white so the facial features read as light. Painted
   with mix-blend-mode: screen so the glyph's darks drop away and only the light
   face features glow over the dark orb. It is a static, centred, inset watermark
   that scales with the orb (inset-positioned), carries no animation of its own
   (reduced-motion safe) and stays subtle across every state tint. Inlined as a
   data URI, so there is no separate static asset to serve. */
